Abstract

Provided is a sliding member, method for manufacturing sliding member, and compressor swash plate using sliding member in which adhesion between the substrate and the resin is enhanced, and which has the excellent durability whereby peeling of the resin film from the substrate does not occur due to prolonged sliding even under harsh load conditions. The sliding member provides a substrate irradiated laser light with energy intensity per unit area of 0.053 J/mm 2 or more and configured an uneven part formed toward a vertical direction by the irradiated laser light and a melted and solidified portion on the uneven part and a resin film including solid lubricant and a binder resin on the substrate.

First claim

The invention claimed is:

1. A slide member comprising:
a substrate having an uneven surface comprising a plurality of convexities;
a plurality of solidified molten portions provided on the uneven surface; and
a resin film comprising solid lubricant and a binder resin, the resin film being provided on the substrate;
wherein each of the plurality of solidified molten portions is formed in a shape of a parallelepiped;
wherein a length of the solidified molten portion is 15 μm or less and a number of the solidified molten portion per unit area is approximately 75 units/mm 2 .

2. The slide member according to claim 1 ,
wherein a height of the convexities is 45 μm or less.

3. The slide member according to claim 1 ,
wherein the solid lubricant is selected from any one of molybdenum disulfide (MoS 2 ), graphite, h-BN, tungsten disulfide (WS 2 ), Pb, or CF.

4. The slide member according to claim 2 ,
wherein the solid lubricant is selected from any one of molybdenum disulfide (MoS 2 ), graphite, h-BN, tungsten disulfide (WS 2 ), Pb, or CF.
